Yes, after the acquisition, webMethods IS is the runtime component and what confuses me is the below details (marked in bold), is there any other runtime component apart from IS or a connector that can access the on-premise apps from built.io?
Firewall Friendly IPs
webMethods.io Integration connects with most third-party services easily and instantly. However, in some cases, you may need to connect to your servers from specific IP addresses, and access resources that lie behind a protective firewall.
This can be achieved in webMethods.io Integration. We provide a set of static IP addresses that you need to whitelist in your firewall. This will allow webMethods.io to make connections to your servers (in order to SSH or to access services like MySQL) and run the required workflow successfully.
To establish the connectivity between webMethods.io Integration and your on-premise Integration Servers, please whitelist the below IPs:
34.215.231.20/32
54.69.161.230/32
35.163.64.191/32
To have the on-premise connectivity working, please whitelist the below IPs:
54.68.140.56/32
54.69.65.75/32
34.215.87.51/32
